CONSTRUCT VALIDATION OF A MEASURE TO ASSESS SUSTAINABILITY OF SCHOOL‐WIDE BEHAVIOR INTERVENTIONS

This study assessed aspects of construct validity of the School‐wide Universal Behavior Sustainability Index–School Teams (SUBSIST), a measure evaluating critical features of the school context related to sustainability of school‐wide interventions. Participants at 217 schools implementing School‐wide Positive Behavior Support (SWPBS) were administered the measure. A two‐step cluster analysis was performed to classify schools based on responses to the 39 SUBSIST items. A two‐cluster solution was obtained, with schools in one cluster (n = 139) obtaining significantly higher scores on SUBSIST items than schools in the other cluster (n = 78). The most critical item that contributed to cluster formation was the use of data for decision making. Results also showed that higher sustainability scores were associated with increased frequency of school team meetings, presentation of data to school staff, access to an external coach/consultant, and greater number of years implementing SWPBS. These results are discussed with regard to implications for sustaining school‐wide interventions.     

‘Think of others’ in knowledge management: making culture work for you

Knowledge management has an important role to play in both organizational and national cultures. In order to have a paradigm shift from a knowledge hoarding to a more knowledge-sharing culture, knowledge management should be used as part of the human capital strategy for the organization. The impact of culture on knowledge management has been studied widely, but little has been written on how knowledge management can affect organizational culture. This paper provides a thought-piece on addressing this overlooked area.     

Bridging the Partisan Divide? Exploring Ambivalence and Information Seeking Over Time in the 2012 U.S. Presidential Election

Research has shown that holding conflicted attitudes (ambivalence) about political decisions may lead people to act as ideal citizens. One example of this normatively ideal behavior is seen in research linking ambivalence to information seeking. To expand on this line of inquiry, this study examines the over-time relationship between ambivalence and information seeking. We use three-wave panel data collected during the 2012 election to determine whether over-time relationships exist between these variables and test the causal direction of these relationships. We find that use of counterattitudinal information increases ambivalence, which leads people to seek out more counterattitudinal information. We also find that use of pro-attitudinal media decreases levels of ambivalence.     

Reading and the Neurocognitive Bases of Statistical Learning

ABSTRACT

The processes underlying word reading are shaped by statistical properties of the writing system. According to some theoretical perspectives, reading acquisition should be understood as an exercise in statistical learning (SL). SL involves the extraction of organizing principles from a set of inputs. Several lines of research provide convergent evidence supporting the connection between SL and reading acquisition. An obstacle to fully appreciating the theoretical and educational implications of these findings is that SL is itself not well understood. In this article, we review the current literature on SL with a particular focus on organizing this literature by grounding it in theories of learning and memory more generally. This approach can clarify the nature of SL and provide a framework for understanding its role in reading, reading acquisition, and reading disorders.     

基于PCA-CMAC的设备性能退化评估

提出了一种用于设备性能退化评估的PCA-CMAC(主成分分析-小脑模型节点控制器)模型.该模型利用PCA进行特征提取,去除多个传感器信号特征的冗余信息,并且减少CMAC的输入维数;利用CMAC的局部泛化能力定量地评估设备的性能退化.给出了模型的实现过程,并将模型应用于钻削过程刀具状态的评估,试验结果证明该模型能基于刀具的正常状态,对刀具的磨损状态进行定量的评估.分析了CMAC中泛化参数g和量化参数r对评估结果的影响,g越大,CMAC的泛化能力越好,但各退化状态之间的区别越不明显;r越小,各退化状态之间越容易区分,但所需的权存储空间越大.2个参数的基本选择原则是CMAC的权存储空间应尽量小,与此同时,各退化状态之间应容易区分.
